In a large bowl, combine beef, Power Blend, garlic, green onions, hoisin, ginger, sesame oil, and hot sauce. To assemble the dumplings, place wrappers on a work surface. Spoon 1 tablespoon of the beef mixture into the center of each wrapper. Using your finger, rub the edges of the wrappers with water. Fold the dough over the filling to create a half-moon shape, pinching the edges to seal. Heat vegetable oil in a large skillet over medium heat. Add potstickers in a single layer and cook until golden and crisp, about 2-3 minutes per side. Serve immediately with soy sauce, if desired.
